A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these cosmic collisions generate ordinary matter or something different. The ...

Astronomers recently announced that they have found a novel explanation for a rare type of super-luminous stellar explosion that may have produced a new type of object known as a quark star.

Simulation of two neutron stars colliding (Credit: C Breu, L Rezzolla) Gravitational waves could be the key to detecting a new phase transition to quark matter when two neutron stars merge. In ...

In the middle of the glowing gas cloud of a supernova remnant, about 8,000 light years away, sits the crushed heart of a dead star. Astronomers recently discovered that this neutron star left behind ...

A quark is an elementary subatomic particle; three of them make up a proton or a neutron. Some scientists base the suggested existence of quark stars (which would be made of quarks instead of complete ...

For a large star, death is a bit of a squeeze. Once its nuclear fuel is spent, its core collapses, sparking a dramatic supernova explosion that blasts away the outer layers. The body left is a cold, ...
